Twin outlet port pumps offer the convenience of using only one intake for both the livewell and raw water wash down pump. The 3/4" tapered inlet connects directly to the sea cock and the upper outlet port provides a continuous flow of water through the 3/4" discharge to the live well while the lower outlet port connects to the wash down pump through either a 1/2" or 3/4" port. New high pressure inlet seal easily handles the higher pressures created by high speed pickups commonly used.
I purchased this with a wash down pump combo pack, now that I'm getting to the point of insulations I notice that the pump is for a thru hual. I have a pootoon and was needing to install the pump on the outside on the pontoon. Will this pump work because it will be under water. Thanks Vincent?
The Johnson Pumps Twin Port 550 GPH -is designed more for a fiberglass boat that uses a thru hull fitting through the bottom of the boat.
